The modern construction industry moves at a relentless pace, leaving very little room for logistical delays or material shortages. For rendering contractors across the UK, the ability to source high-quality, coloured finishes quickly is often the difference between a profitable week and a costly setback. Traditionally, obtaining a specific shade of silicone or acrylic render involved a lengthy waiting period while the manufacturer processed a factory order. This could take anywhere from several days to a fortnight, depending on the complexity of the colour and the current demand at the production plant. However, the introduction of professional topcoat tinting facilities at EJL Supplies has completely revolutionised this workflow for local tradespeople. By bringing industrial-grade mixing technology directly into the merchant’s warehouse, we have eliminated the primary bottleneck in the external wall insulation and rendering process.
Having the ability to walk into a store and leave with a custom-tinted product on the same day is a massive advantage for any rendering business. It allows for a level of agility that ensures site productivity remains high even when unexpected changes occur. For instance, if a project requires more material than originally estimated, a contractor no longer has to wait for a delivery from a distant factory. They can simply visit our Portsmouth branch and have the additional tubs matched perfectly to their existing batch. This reliability is why more professionals are shifting their loyalty toward merchants who invest in tinting facilities rather than those who rely solely on pre-mixed stock. It is about providing a service that mirrors the expertise of the people using the products on a daily basis.
The Technical Edge of In-House Topcoat Tinting Facilities
Precision is the most critical factor when it comes to mixing high-performance renders. When we talk about our topcoat tinting systems, we are referring to a sophisticated system of computer-controlled dispensers and high-speed gyroscopic mixers. These machines are designed to interact seamlessly with the proprietary software provided by Jub and Fassa Bortolo. This integration ensures that every single tub produced meets the exact chemical and aesthetic specifications set out by the manufacturer. The pigments used are highly concentrated and UV-stable, meaning the colour you choose will remain vibrant for decades despite the harsh British weather. By maintaining these standards, EJL Supplies ensures that the finished result on the wall is indistinguishable from a factory-mixed alternative.
The process begins with a base material that is formulated to accept specific pigment loads. Depending on the desired final shade, we use either a white base or a transparent base to ensure the depth of colour is accurate. The topcoat tinting facilities then dispense the exact millilitres of colorant required, following a digital recipe that is accurate to a fraction of a gram. This level of detail is impossible to achieve through manual mixing on a construction site, which often leads to “shading” or inconsistent patches on the finished elevation. By choosing a professional tinting service, the contractor removes the risk of human error and ensures a uniform, professional finish every time. This consistency is vital for maintaining a reputation for quality in the competitive rendering market.

Same-Day Custom Colours for Jubizol Systems
Jub is a brand synonymous with quality and innovation in the thin-coat render sector. Their Jubizol systems are a staple for many UK contractors due to their excellent workability and durability. One of the primary reasons why EJL Supplies invested in dedicated topcoat tinting facilities for Jub products is to give our customers access to the full Jubizol colour palette without the wait. Whether a client requires a subtle pastel tone or a bold, contemporary grey, our machines can produce the exact match in minutes. This service is particularly useful for contractors working on large-scale housing developments where colour consistency across multiple plots is a non-negotiable requirement.
The flexibility offered by our in-house systems also extends to the different types of Jub finishes available. We can tint silicone, silicate, and acrylic topcoats, each of which offers different technical benefits depending on the substrate. Silicone renders are highly breathable and water-repellent, making them the ideal choice for most modern builds. By utilising our topcoat tinting facilities, you can ensure that these technical properties are preserved while still achieving the exact aesthetic the architect has specified. The pigments are thoroughly integrated into the render during the mixing process, which prevents the “streaking” that can sometimes occur with lower-quality tinting methods. This ensures that the product performs exactly as intended by the Jub technical team.
Achieving Perfection with Fassa Bortolo Tinting Services
Fassa Bortolo is another titan of the rendering industry, known for their comprehensive range of systems including the ever-popular Fassacouche and their various silicone-siloxane finishes. At EJL Supplies, we recognize that Fassa Bortolo users demand a very high standard of technical support. Our topcoat tinting facilities are fully equipped to handle the Fassa Bortolo colour system, providing an almost limitless range of possibilities for external facades. This is especially important for heritage projects or renovations where the new render must match an existing building material or a specific historical shade. Our team can help you navigate the colour charts to find the perfect solution for your specific project.
Using the official Fassa Bortolo tinting pastes within our machines ensures that the warranty of the system remains valid. Many manufacturers will not guarantee a product if it has been tinted using third-party pigments that have not been tested for compatibility. By using our topcoat tinting facilities, you are guaranteed that the product is mixed using the correct components as specified by the manufacturer. This protection is invaluable for contractors who need to provide long-term guarantees to their clients. It shows a commitment to using the best possible materials from the base coat right through to the final tinted topcoat. The result is a facade that not only looks incredible upon completion but continues to protect the structure for years to come.
Improving Site Efficiency and Reducing Waste
One of the often-overlooked benefits of having local access to tinting technology is the reduction in material waste. When a contractor is forced to order factory-mixed render, they often over-order to ensure they do not run out mid-job. This leads to excess tubs sitting in a warehouse or, worse, being discarded at the end of the project. Because EJL Supplies provides topcoat tinting facilities on-site, you can order exactly what you need for the initial application. If you find yourself a few tubs short as the project nears completion, you can simply call us or drop by the store to have more produced instantly. This “just-in-time” delivery model saves money and is far more environmentally friendly.
Site efficiency is also boosted by the elimination of “downtime.” In the rendering trade, waiting for materials is one of the most common causes of project delays. When the scaffolding is up and the weather is clear, every hour counts. Having a reliable partner with in-house topcoat tinting facilities means you can capitalise on good weather windows. You can pick up your materials in the morning and have them on the wall by lunchtime. This speed of service allows you to move from one project to the next more quickly, increasing your annual turnover and improving your overall business profitability. It is a practical solution for a practical trade, designed to keep your team working rather than waiting.
Furthermore, the consistency of our tinted products means that application is smoother and faster. Because the pigment is perfectly dispersed within our topcoat tinting facilities, the render maintains its intended consistency and “open time.” This makes it easier for the plasterer to achieve a flat, even finish without having to fight the material. When a product is easy to apply, the quality of the workmanship naturally improves. This leads to fewer snagging issues and a higher level of client satisfaction. For a specialist merchant like EJL Supplies, providing these tools is part of our mission to support the trade with the best possible service.
Why Technical Expertise Matters in Render Tinting
While the machinery does the heavy lifting, the human element of our service is just as important. The staff at EJL Supplies are not just retail assistants; they are experts who understand the chemistry of the products they are mixing. When you use our topcoat tinting facilities, you are also gaining access to decades of industry knowledge. We can advise on which base coat is best for your specific substrate and which topcoat will provide the best longevity for t
he location of the building. For example, a coastal property will have very different requirements than an inland renovation, and we can guide you toward the right tinted solution for each.
The software we use also tracks the Light Reflectance Value of every colour we produce. This is a critical technical detail because dark colours with low LRVs can absorb too much solar heat, which may cause thermal movement and cracking in the render. Our team will check this for you as part of our topcoat tinting facilities service, ensuring that your colour choice is safe for the specific insulation system you are using. This level of technical oversight prevents costly mistakes and ensures the durability of the finished facade. It is this attention to detail that sets a specialist rendering merchant apart from a general builder’s merchant. We are here to ensure that your project is a success from start to finish.
Finally, we take great pride in the upkeep and calibration of our equipment. To ensure the highest levels of accuracy, our topcoat tinting facilities undergo regular maintenance and software updates. This ensures that the “Salmon Pink” you order today is exactly the same as the one you might order for a different project next year. We store digital records of your previous orders, making it incredibly easy to re-order the exact same shade whenever you need it. At EJL Supplies, we are committed to being the most reliable link in your supply chain. We invite you to visit our Portsmouth store to see our tinting technology in action and discuss how we can support your next rendering project with professional, on-demand colour solutions.
Frequently Asked Questions About Our Services
Can I get a custom colour matched in store?
Yes, our advanced topcoat tinting facilities allow us to match a vast array of colours from various palettes beyond just the standard Jub and Fassa Bortolo charts. If you provide us with a physical sample or a specific RAL or NCS code, we can usually find a corresponding formulation within our system. This bespoke service is perfect for contractors working on restoration projects where an exact match to existing masonry is required. It ensures that any new extensions or repairs blend seamlessly with the original structure.
How long does the tinting process take?
The actual mixing process is remarkably fast, usually taking only a few minutes per tub once the colour has been selected and the base material loaded. For small orders of five to ten tubs, we can often complete the work while you wait in the store. For larger project requirements, we recommend calling ahead so our team can utilise the topcoat tinting facilities to prepare your order for a specific collection time. This allows you to keep your site team moving without any unnecessary waiting around.
Is there a minimum order for tinted render?
One of the greatest benefits of our in-house service is the lack of restrictive minimum order quantities. Unlike factory orders which often require a full pallet or a significant surcharge for small batches, our topcoat tinting facilities can process as little as a single 25kg tub. This is ideal for small patch repairs, feature walls, or for contractors who just need a tiny bit more material to finish a gable end. It provides total flexibility for projects of all sizes, from a small domestic porch to a large commercial block.
